Motta et al (2020 - PMID: 32721402) report on 7 unrelated individuals harboring de novo missense MAPK1 pathogenic variants.

The phenotype corresponded to a neurodevelopmental disorder and - as the authors comment - consistently included DD, ID , behavioral problems. Postnatal growth delay was observed in approximately half. Hypertelorism, ptosis, downslant of palpebral fissures, wide nasal bridge as low-set/posteriorly rotated ears were among the facial features observed (each in 3 or more subjects within this cohort). Together with short/webbed neck and abnormalities of skin (lentigines / CAL spots) and growth delay these led to clinical suspicion of Noonan s. or disorder of the same pathway in some. Congenital heart defects (ASD, mitral valve insufficiency, though not cardiomyopathy) occurred in 4/7. Bleeding diathesis and lymphedema were reported only once.

MAPK1 encodes the mitogen-activated protein kinase 1 (also known as ERK2) a serine/threonine kinase of the RAS-RAF-MEK-(MAPK/)ERK pathway.

MAPK1 de novo variants were identified in all individuals following trio exome sequencing (and extensive previous genetic investigations which were non-diagnostic).

The distribution of variants, as well as in silico/vitro/vivo studies suggest a GoF effect (boosted signal through the MAPK cascade. MAPK signaling also upregulated in Noonan syndrome).

Fetal anomalies v0.2364 TECPR2 Zornitza Stark changed review comment from: SPG49 is an autosomal recessive complicated form of spastic paraplegia. PMID 23176824 reported 4 Jewish Bukharian individuals homozygous for same founder variant and delayed psychomotor development, intellectual disability, and onset of spastic paraplegia in the first decade. Affected individuals also had dysmorphic features, thin corpus callosum on brain imaging, and episodes of central apnea, some of which were fatal. Three additional patients from unrelated non-Bukharian families reported in PMID 26542466, harboring two novel variants (c.1319delT, c.C566T) in this gene. In addition to intellectual disability and evolving spasticity, autonomic-sensory neuropathy accompanied by chronic respiratory disease and paroxysmal autonomic events were prominent.
